摘要:
为探讨巨型钢框架结构二阶位移的实用算法,本文从简化结构计算模型入手,采用连续化概念和刚度等效原则,将格构式巨型构件等效为实腹式构件,获得巨型钢框架结构的等效模型,并用一列假想的承担各楼层竖向荷载的刚性杆与其并联,获得该结构的二阶简化计算模型,据此建立结构的二阶分析刚度方程,并用工程实例验证了本文方法的实用性与可靠性.算例表明:次结构对结构总体抗侧移的贡献很小,可忽略不计; 在计算结构整体位移时,可不考虑等效节点域剪切变形的影响.该方法无需迭代即可完成结构的二阶分析,计算快速方便,且精度能满足工程设计的要求,可供结构方案设计参考.
Abstract:
To study a practical approach of second order displacements for huge steel frames, an equivalent model for the huge steel frame structure is established according to continuous concept and stiffness equivalent principle. Considering second order effect of the structures, a practical model of second order analysis is proposed, and the stiffness equation of second order analysis for the model is established. The feasibility and reliability of the methods are verified by practical example. The results show that the effects of second structures and equivalent joint-panel shear deformation on global structural deflection can be neglected and iteration can be avoided for second order analysis. The calculation is very quick and convenient and analysis precision can meet the demands in practical design.
